What are the advantages and disadvantages of using free shop systems versus creating a custom PHP-based shop?

When deciding between using a free shop system and creating a custom PHP-based shop, it is important to consider the advantages and disadvantages of each option. Free shop systems offer a quick and easy way to set up an online store with minimal coding required. However, they may lack customization options and flexibility compared to a custom PHP-based shop. On the other hand, creating a custom PHP-based shop allows for complete control over the design and functionality of the online store but requires more time and expertise to develop.

// Example of creating a custom PHP-based shop
<?php

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myshop";
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Create a table for products
$sql = "CREATE TABLE products (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(30) NOT NULL,
    price DECIMAL(10,2) NOT NULL,
    description TEXT
)";

if ($conn->query($sql) === TRUE) {
    echo "Table products created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

$conn->close();

?>
